Letters Patent No. l11,781,.dated February 14 1871.

IMPROVEMENT IN CULTIYATORS.

The Schedule referred to in these Letters Patent and making pan: of the same.

which will enable others skilled in the art to make and luse the same, reference being had to the accompanying drawing forming part "of this specification.

Figure l is a detail sectional view of my improved cnltivator, taken through the line a; x, g.2.

Figure 2 is a rear Viewl of the same partly in section, to, show the construction.

Figure 3 is a detail sectional view ot' the same, taken through the line y y, tig. 1.,

Similarlettcrs of reference indicate corresponding parts.

My invention relates to cultivators, and consists in the mode of combining the frame and axles, as hereinafter more-particularly described and subsequently exemplified in the claim.

A are the wheels of the cultivator, which revolve upon and are' secured to the journals of the axles B in the ordinary manuel'.

U is a har, which vis bent twice at right angles or nearly at right angles, and the ends ot' which are se` curely attached to the inner ends of the axles B, thus forming a space beneath the body of the cultivator, to enable it to pass over the plants being cultivated without injuring them.

D is a bar, which is bent twice at an obtuse angle, so that, while' its .middle or horizontal part may rest upon the horizontal middle part ofthe bar B, the ends of the bar D may reach the axles B near the wheels A and be secured to said axles by a clip, E, and yoke F, a block, G, heilig interposed between the Said axles andthe ends ot' the. said bar l), it' de sired.

S is the tongue, which may be secured to the hor.- izontal parts oi' the bars O D by the same boltsthat secure the saidparts of the said bars to each other.

VH are the plow-beams, tw'o of' which are connected with cach axle B.

The beams of each pair are made of diierent lengths, so that one. ot' the plows may work in advance ot" the other.

'lhc forward ends of the b'eains ot' each pair are placed one upon 'each side ofthe bar I, to which they are secured by two bolts, the rear bolt passing through a slot in the'rear part of the said bar, as shown in iig. 1, so that, by loosening the said rear bolt, the plows maybe adjusted to work deeper or shallower lin the ground. as may be desired.

In the forward ends of the short bars'Iis formed I an eye, through which passes the bolt J, 'which also passes through the rear ends of the clip K,.so as to allow the plows to have a free lateral movement, while, at the same time, they are always held in an erect position'.

L are boxes, each of which ismade in two parts, placed one above and the other below the axle B, the concaves or recesses of said boxes being made so shallow that the ends of said parts will not touch each other, as shown in g. 1.

The boxes L are secured to the axles B by the clips or bands K, as shown in-figs. l and 2.

M is a set-screw that passes through the upper part or arm of the clips or straps K, and the forward end of which rests against the upper part or halt' of the said boxes L, so that, by turning the said screw M, the wear ofthe boxes may be taken up, causing the said boxesto always 't snugly upon the said axle. This construction allows the plows to have'a free verf tical movement.

The rear ends ofthe beams H are bent downward and the forward edges of their lower ends are rounded od, the rear edges being left square, as 'shown infigs. 1 and 3.

N are the plows, upon the rear sides of which are formed eyes, O, having their rear sides concaved to fit upon the rounded forward edge of the lower ends of the plow-beams H, and having their forward sides convex or rounded to receive the clips P, the ends of 'the arms of which have holes or eyes formed in them to receive the hooks ofthe hook-bolts Q which pass through the. holes ot' the yoke It and are secured by' nuts.

c This construction enables the plows N to he adjusted squarely upon their seats, or inclined to throw the soil to the right or le't or toward orV from the plants, as may be desired.

Having thus described my invention,

I claim as new and desire to secure'by Letters Patent- The axles B B, each extending out about one-third the distance between the hubs of the wheels, combined as described, with a right-angled bar, O O, and obtuse-angled bar, D 1), the former fastened to said axles at the outer part and the latter at the inner part near'thc hub,'all as and for the purpose set forth.
